Golden jackals are obligatory monogamous breeders with long-term pair bonds. Both members of the pair jointly defend their territory, normally produce 1 litter per year and raise their offspring together, with successive litters probably being full siblings. Some pups remain on the natal territory and help care for next year's litter as reproductively suppressed subordinates before they disperse. Why did older offspring stay and help as subordinates, rather than disperse and breed elsewhere, and why did parents allow older offspring to stay on the natal territory? Under the reproductive skew concession model, such helping is expected if ecological constraints are intense and dispersal chances are low but should be less likely if ecological constraints are relaxed. We tested this idea by analyzing data from golden jackals on the Serengeti short-grass plains from 1977 to 1990 when the intensity of ecological constraints changed 3-fold. We collected data on the annual reproductive success of dominant breeders with and without support from helpers, the tenure of territorial breeders, and the number of breeding slots accessible to subordinates elsewhere, and used these to assess the fitness consequences of different reproductive roles and the likelihood of reproductive conflict. Between 1977 and 1984, the quantitative analysis of territorial tenureship showed that subordinates faced the difficulty of acquiring a breeding slot elsewhere as a major ecological constraint, with their best option either to help or, theoretically, to breed on the natal territory. After the arrival of parvovirus in 1985-an exotic pathogen lethal to pups-the number of available breeding slots rose strongly, relaxing ecological constraints. However, some subordinates continued to help, thus losing the reproductive conflict with dominants over their optimal breeding role. In golden jackals, the frequent observation of helping may therefore reflect resolution of the potential reproductive conflict in favor of the dominant breeder, as selection pressure on the dominant to recruit subordinates as helpers is stronger than the selection pressure of subordinates to resist. The theoretical exploration of fitness benefits of different reproductive tactics under different levels of ecological constraints calibrated with empirical fitness benefits illuminated why polygamy and/or multiple monogamy is rare or nonexistent in Serengeti golden jackals.</p>","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"107 2","pages":"228-239"},"PeriodicalIF":1.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13035267/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147595850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limited availability of energy-efficient, or optimal, prey can be a key determinant of the conservation status of mesocarnivores-thus investigating diet habits during reintroduction efforts can provide insights into the trajectory of a reestablishing population. The reintroduction of fishers (<i>Pekania pennanti</i>) in Washington state, United States, offers an opportunity to assess diet variation across reintroduction areas using high-resolution DNA metabarcoding methods. We assessed Fisher diet in 2 reintroduction sites in the Cascade Mountains of Washington (the South Cascades and the North Cascades) where fishers performed differently across multiple metrics used to measure initial reintroduction success. We had the rare opportunity to test correlations between metabarcoding relative read abundance and prey biomass consumption while fishers were fed a known diet while in captivity. We found a moderately positive, though highly variable, correlation (<i>r = </i>0.47) between approximate biomass consumption of food items and relative read abundance within individual diet samples; however, we detected a strong, though statistically insignificant, correlation between relative read abundance and prey biomass when looking at the relative importance of prey groups in aggregated diet profiles (<i>r = </i>0.72). We collected 300 Fisher scats and gastrointestinal tracts using telemetry and scat detection dog teams to characterize diet profiles. We found strong, positive correlations between relative read abundance and frequency of occurrence metabarcoding summaries. Hares and rabbits (<i>Lepus americanus</i> and <i>Sylvilagus floridanus</i>) were the most prevalent prey in both populations (North Cascades = 17%, South Cascades = 68%), but there were significant compositional differences between diets of the reintroduced populations. South Cascades fishers had limited prey diversity (<i>n</i> = 19 taxa), whereas 71 taxa were represented in the North Cascades Fisher diet. The diet composition of fishers in the South Cascades was akin to populations in the central and eastern United States, where range expansions are facilitated by access to optimally sized (>250 g) prey. In contrast, the diverse diet of North Cascades fishers was more similar to populations at the southernmost extent of their range (Oregon and California), where optimally sized prey is scarce and population recovery is stunted. The surprisingly high levels of dietary variation among adjacent reintroduction sites highlight the utility of diet studies in evaluating whether translocated populations are obtaining adequate resources to support population establishment and thus informing subsequent management interventions.</p>","PeriodicalId":50157,"journal":{"name":"Journal of Mammalogy","volume":"107 2","pages":"252-263"},"PeriodicalIF":1.6,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13035265/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147595814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
